About WIB (Western Indonesia Time)

The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.

East Africa Time (EAT) is used in the countries of East Africa including Kenya, Ethiopia, Tanzania, Uganda, and others. EAT does not observe daylight saving time and shares the same offset as Moscow Standard Time (MSK).
